LUBRICATION DIAGRAM

550 301 13 LUBRICATION DIAGRAM is one of those components that's absolutely key for getting grease or oil exactly where it needs to be, especially on the feed beam, the rotation unit, or even the drifter's front head. It’s not just a simple fitting; usually, it’s a metering valve or a distribution block designed to split and deliver a precise shot of lubricant to multiple points. This ensures all those pins, bushings, and sliding surfaces get their regular feed, keeping friction down and preventing premature wear.

When this part starts to give up the ghost, you’ll usually notice it first through other symptoms. Maybe a bearing on the feed motor starts running hotter than it should, or you hear a distinct squeak from a pivot point that used to be quiet. Sometimes, the auto-lube system pressure might fluctuate wildly, or you might even get a 'low lube pressure' alarm if it’s completely blocked or leaking internally. What often happens is that one specific point, like a feed chain roller or a drifter guide, just stops getting its grease, leading to accelerated wear and eventually, a seized component.

When you're swapping one of these out, it’s not just a simple bolt-on job. Always take a good look at the lines connecting to it – check for kinks, blockages, or any signs of previous leaks that might have starved the system. A common oversight is not properly purging the air from the new component and its lines after installation, which can lead to initial starvation and a false sense of security. Make sure the system cycles a few times to push fresh grease through everything.
